@TheBl4ckSh33p Hi! Unfortunately, when existing furniture is sold, items are depreciated by 20%. For example, if I buy a new Crisponix Budget fridge, the cost is $375 but if I sell the existing one I only get $300 for it. That depreciation will be true for every item on the lot (including the landscaping plants). Also, the cost of the new lot may be a factor. The value of my sim's current house and lot is $14,982 but when placed on a different (also larger) lot the value is $17,317. The only way I know to avoid losing some of those simoleons would be to have your sim keep furniture when moving and buy the lot unfurnished. Although, then you will have to place all of the furniture on the new lot. At $17K, I'm guessing you have a fair amount of stuff on your lot, so placing it all again might be annoying. :-/
Edit: You could use the money cheat to recover the loss. If you're playing on console though, enabling cheats may disable achievements and trophies.
2nd edit: Actually, if you don't mind using cheats, I completely forgot about the free real estate cheat. If you enter that at the manage worlds view, while your sims are moving, you will keep all your simoleons.
